What is the use of a BSA Calculator?
A Body Surface Area (BSA) calculator is a tool used in healthcare to estimate the surface area of a human body. BSA is widely used in medical settings for calculating drug dosages, determining metabolic rates, and assessing cardiac index. It provides a more accurate measure for these calculations than body weight alone. This tool is especially important for pediatric and oncology patients to ensure safe and effective treatment dosages.
What is the formula for calculating BSA?
One common formula for BSA is the Mosteller formula: BSA = sqrt((Height(cm) x Weight(kg)) / 3600).
How to use the BSA Calculator website?
Enter your height in centimeters and weight in kilograms into the respective input fields. Click the "Calculate BSA" button to compute your Body Surface Area. The result will appear below the calculator, along with the formula used for the calculation. You can clear the inputs using the "Clear" button.

Frequently Asked Questions
1. What is a BSA calculator?
A BSA calculator is a tool that calculates the body surface area of an individual. It is commonly used in medicine to determine dosages for medications, especially in cancer treatment, and to assess overall health indicators.
2. Why is BSA calculation important?
BSA calculation is important because it helps healthcare professionals determine drug dosages and other medical metrics that are more accurate than those based solely on weight or height.
3. What is the Mosteller formula for BSA?
The Mosteller formula for calculating BSA is: BSA = sqrt((Height(cm) x Weight(kg)) / 3600). It is simple and widely used in clinical settings.
4. Can I use BSA for pediatric cases?
Yes, BSA calculations are particularly important in pediatrics to ensure proper medication dosages for children based on their body surface area rather than weight alone.
5. What units are used for BSA?
The calculated BSA is usually expressed in square meters (m2).
6. Is BSA accurate for all body types?
BSA provides a standardized measurement, but it may not account for variations in body composition. Consult a healthcare professional for specific cases.
7. Can I use the BSA calculator for animals?
While primarily designed for humans, similar formulas are used for animals. Ensure you use appropriate formulas for veterinary purposes.
8. How often should I calculate my BSA?
BSA doesn’t change frequently. Calculate it when needed, such as during medical evaluations or medication adjustments.
9. What other formulas exist for BSA?
Other formulas include the DuBois and DuBois, Haycock, and Gehan and George formulas. The choice depends on the application and precision required.
10. Are online BSA calculators reliable?
Yes, online BSA calculators are reliable if based on established formulas. Always cross-check results with a healthcare provider for medical purposes.
